Note that in the limit \(A\rightarrow 0\) , the perturbation spectrum
parameters coincides with brane-inflation [1]} in particular for \(\alpha =1\) . Also, in the low-energy limit, \((A+V^{\left( \alpha +1\right)})^{\frac{1}{\alpha +1}}\ll \lambda \) , the slow-parameters reduce to the
standard form [2]}.
